Sometimes, while working with Python data, we can have a problem in which we need to assign particular value as per certain condition. One of condition can be non-max, min element. This kind of task can occur in many application of day-day programming and competitive programming. Lets discuss certain ways in which this task can be performed.

Input :
test_tuple = (3, 6, 3, 6, 34, 34)
K = None
Output : (3, None, 3, None, 34, 34)

Input :
test_tuple = (3, 34)
K = None
Output : (3, 34)

Method #1 : Using max() + min() + tuple() + loop
The combination of above functions can be used to solve this problem. In this, we perform the task of finding minimum and maximum element using min() and max() and brute force to assign all excepted elements to K.




# Python3 code to demonstrate working of 
# Assign K to Non Max-Min elements in Tuple
# Using min() + max() + loop + tuple()
  
# initializing tuple
test_tuple = (5, 6, 3, 6, 10, 34)
  
# printing original tuple
print("The original tuple : " + str(test_tuple))
  
# initializing K 
K = 4
  
# Assign K to Non Max-Min elements in Tuple
# Using min() + max() + loop + tuple()
res = []
for ele in test_tuple:
    if ele not in [max(test_tuple), min(test_tuple)]:
        res.append(K)
    else:
        res.append(ele)
res = tuple(res)
  
# printing result 
print("The tuple after conversion: " + str(res))

Output :

The original tuple : (5, 6, 3, 6, 10, 34)
The tuple after conversion: (4, 4, 3, 4, 4, 34)

 

Method #2 : Using generator expression + max() + min() + tuple()
This is one liner approach by which this task can be performed. In this, we extract all the elements and assign with appropriate condition using generator expression.




# Python3 code to demonstrate working of 
# Assign K to Non Max-Min elements in Tuple
# Using generator expression + max() + min() + tuple()
  
# initializing tuple
test_tuple = (5, 6, 3, 6, 10, 34)
  
# printing original tuple
print("The original tuple : " + str(test_tuple))
  
# initializing K 
K = 4
  
# Assign K to Non Max-Min elements in Tuple
# Using generator expression + max() + min() + tuple()
res = tuple(ele if ele in [min(test_tuple), max(test_tuple)] else K for ele in test_tuple)
  
# printing result 
print("The tuple after conversion: " + str(res))

Output :

The original tuple : (5, 6, 3, 6, 10, 34)
The tuple after conversion: (4, 4, 3, 4, 4, 34)
